This is a gross misinformation. amavisd-new behaves pretty much as spamd does, the main difference is that it uses smtp protocol instead of pipe+spamc to talk with MTA. Performance-wise both the amavisd-new and the spamc+spamd are in the same category, and like any other tool, both can be mistuned for a particular environment, and are subject to the same SA setup/tuning/bottleneck-avoidance guidelines. > After carefull studyin this doc : > http://svn.apache.org/repos/asf/spamassassin/branches/3.1/spamd/README , > I've realised that's just the thing I need.
